September was the fourth consecutive month with rainfall significantly above the long term mean, the island’s weathermen say.
The Met Office says total rainfall measured at the airport was 112mm (4.4 inches), 50 per cent more than normal. The wettest day was the 24th with 34.2mm (1.3inches) but nearly three times that amount fell on the hills on that day, leading to some localised flooding.
The mean temperature for the month measured only 13C, 0.7C below the September mean, making it the coldest September since 1994.
The warmest day was September 2, with a maximum of 18.5C. The coldest day was the 22nd with a minimum air temperature of 4.4C at Ronaldsway but some parts of the island experienced their first ground frost of the season.
Despite all the rain, sunshine was slightly above average with 142 hours recorded.
There were no gales during the month but the mean wind speed measured 15.2mph compared to the long term mean of 12.9mph. The strongest winds were recorded on the 14th with a gust of 46mph at Ronaldsway.
Fog was seen on the 8th, there was no thunder or hail at the airport but the latter was reported in the south of the island on the 18th.
